Realization of healthy longevity through development of iPS cell-based cardiovascular medicine

Research Summary

With an aging society such as Japan, the frequency of cardiovascular diseases (diseases affecting the heart and blood vessels) is expected to progressively increase in the future. Heart transplantation is an ultimate therapeutic modality for severe heart failure, however, the availability of hearts for transplantation is quite limited. Thus, there is a need to develop new therapies for severe heart failure to be able to treat more heart patients. Our laboratory is working on discoveries for new cardiovascular medicine through iPS cell technology-based cardiac regenerative therapy and drug discovery research, drawing on our lab head’s clinical experiences as a cardiovascular surgeon to design an experimental plan addressing clinical needs and to conduct studies using surgically established cardiovascular disease animal models. Our goal is to realize the healthy longevity of humans through the development of iPS cell-based cardiovascular medicine.

We are also actively working together with many research institutes and industry partners to advance clinical translational medicine. We are currently working to prepare clinical research studies for cardiac regenerative therapy using human iPS cells in collaboration with Kyoto University and industry partners.

Thick cardiac tissue sheets seen in culture dish

Three-dimensional thick cardiac tissue sheets generated from human iPS cells. Inset: Transplantation of the cardiac tissue sheet into a porcine myocardial infarction model (at MEDDEC, Port Island) (→: Cardiac tissue sheet)

Bio-engineered cardiac tissue capable of self-contraction and comprising various human iPS cell-derived heart cell types.

Transplantation of human iPS cell-derived cardiac tissue into a rat myocardial infarction model. Human myocardium with vascular network was formed in rat heart at 4 weeks after transplantation. Red: Human nucleic antigen, Green: von Willebrand factor (vascular endothelial cell) (Collaboration with University of Louisville, USA)
